A whole-body trauma CT quickly scans the head, neck, chest, abdomen and pelvis after a serious accident. Learn why it is done, how fast it is and what it can find.
A whole-body trauma CT is a fast scan, usually done in minutes, that images the head, neck, chest, abdomen, pelvis and spine after a serious accident. It finds bleeding, organ injuries and fractures that may not be obvious, and helps doctors treat the most life-threatening problems first.
When Is It Used?
After high-energy injury, such as road accidents, falls from height and serious sports or industrial injuries, patients may have injuries inside the body that are not visible. A full CT scan after initial stabilisation quickly maps these. It is done by the emergency team alongside resuscitation. See CT brain scan and CT abdomen and pelvis.
Body regionInjuries that may be foundHead and neckSkull fracture, brain bleeding, neck spine injuryChestRib fractures, lung bruise, collapsed lung, aortic injuryAbdomenLiver, spleen, kidney injury, internal bleedingPelvis and spineFractures, bleedingBlood vesselsActive bleeding (with contrast)How Fast Is It?
Modern scanners can image the entire body in under a minute, and the whole process, including moving the patient, takes about 10 to 20 minutes. Contrast is injected to show bleeding. Doctors review images immediately, and urgent injuries are treated first. See CT scan with contrast.
What It Cannot Replace
It does not replace clinical examination, repeated monitoring or other tests such as ultrasound (FAST scan) at the bedside, blood tests and X-rays. Some injuries, such as small bowel or diaphragm injuries, can be subtle and need repeat examination. Children are scanned with extra care to limit radiation. See CT scan for children.
Radiation and Pregnancy
A whole-body CT gives a high dose, but in severe trauma the benefit of finding life-threatening injuries is much greater than the risk. If the patient is pregnant, doctors use the lowest dose that allows safe treatment. See CT scan during pregnancy and CT scan radiation dose.
A Practical Example
Prakash, 29, is thrown from a motorcycle and arrives with belly pain and low blood pressure. A whole-body CT shows a liver laceration with bleeding and a fracture of the pelvis. A surgeon and an interventional radiologist stop the bleeding within the hour. The scan found injuries not visible on the outside.
What Families Can Do
- Share the patient's history, allergies and medicines with the team
- Keep documents and identity papers ready
- Stay calm and allow staff to work quickly
- Ask for updates from the senior doctor
After the Scan and Next Steps
After the scan, the trauma team may operate, drain blood, place a drain in the chest, or monitor the patient in intensive care. Recovery can include rehabilitation, physiotherapy and psychological support. Follow-up scans may be done to check healing. Keep the scan CDs and reports with discharge papers for future care and insurance claims.
Questions to Ask Your Doctor
- What injuries were found and which are most serious?
- Do any need surgery or only observation?
- Will repeat scans be needed?
- What activity limits should we follow after discharge?
Common Mistakes to Avoid
- Moving an injured person unnecessarily before help arrives.
- Not sharing medicine and allergy information with the team.
- Skipping follow-up and rehabilitation.
Booking, Timing and Report
Most CT scans can be booked on the same day, and the visit takes 20 to 40 minutes. Carry your prescription, old scans and a recent creatinine report if contrast is planned. Reports are usually ready within 24 hours, and images can be provided on a CD or digital link for your doctor.
Key Facts at a Glance
- Trauma CT is fast and finds hidden injuries
- Contrast shows active bleeding
- Radiation is justified in serious injury
- Monitoring continues even after a normal scan
